The effect of aluminosilicate modifying additive on the deformation properties of adhesive dry building mixtures

Abstract

The article provides information about the possibility of using amorphous aluminosilicates as a modifying additive for dry building mixtures. The data on the synthesis of the additive, its chemical and physical properties are given. A recipe for adhesive dry building mixtures with the use of amorphous aluminosilicates is proposed synthesized by the proposed method. The technical and physical properties of tile adhesives made using amorphous aluminosilicates as a modifying additive are considered. The deformative properties of tile adhesive made on the basis of the proposed recipe are considered. The elastic modulus of the coating, shrinkage deformation, ultimate tensile strength, axial tensile strength and crack resistance coefficient are calculated. According to the results obtained, appropriate conclusions were made.

Applications of Calcium Hydrosilicates and Amorphous Aluminosilicates in Lime Dry Mixes

“…1). In order to expand the resource base of modifying additives for lime dry construction mix, it has been proposed in [18][19][20] to use amorphous aluminosilicates. X-ray diffraction analysis revealed that the composition of the additive is represented by the following minerals: tartardite Na 2 SO 4 , gibbsite Al(OH) 3 , minerals of the zeolite group (Fig.…”
